GPGS v2 - Match making tutorial

Hi,

Does anybody know how auto match making is done in gpgs plugin v2?

I’m asking help for it because in my game I can match 1v1 but I can’t match 2v2.

For example: 

I have a button for 1v1 battle:

myApp.gpgs.multiplayer.realtime.create({automatch = {minPlayers = 1, maxPlayers = 1}}) (Works for a 1v1)

and other button for 3 players game:

myApp.gpgs.multiplayer.realtime.create({automatch = {minPlayers = 2, maxPlayers = 2}}) (Never auto match players, and keeps waiting UI without matching players in all three devices)

am I doing something wrong?

Thank you
